M O n m .m/ m W Patented Jan. 17, 1939 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to a pencil and particularly to a pencil of the collapsible type.

The principal object of the present invention is the provision of .a pencil having simple and effectual means whereby the lead and eraser thereof may be shielded.

A further object of this invention is the provision of a pencil having a sleeve mounted for limited longitudinal movement along the lead carrying member, and a sheath adapted to be frictionally secured over either end of said lead carrying member, to contact said sleeve.

Other objects are simplicity and economy of construction, ease of operation, and adaptability to pencils wherein the leads are stationary or adjustable. 7

With these objects, and others which will appear during the course of the specification, in View, reference will now be had to the drawing, wherein:

Figure l is a perspective view of the pencil, shown in the closed or inoperative condition.

Fig. 2 is a perspective view of the pencil in the operative position.

Fig. 3 is a perspective view of the pencil in the operative position, with the sheath removed to permit erasing.

Fig. 4 is an enlarged longitudinal, sectional view, with the parts in the operative position.

Fig. 5 is a cross sectional View, taken on line V-V of Fig. 4.

Fig. 6 is a longitudinal, sectional view, showing the pencil in the closed position.

Fig. 7 is an enlarged, elevation of the lead carrying member, with the ferrule and eraser attached.

Fig. 8 is a longitudinal, sectional view of the sleeve.

Fig. 9 is a view similar to that shown in Fig. 8, with the bosses in transverse, offset relation, and,

Fig. 10 is an end elevation of the modified form shown in Fig, 9.

Throughout the several views, like reference characters designate similar parts, and the numeral 52 indicates a lead carrying member, such as the ordinary wood member, with a lead l4 glued therein, or a mechanical lead pencil might be substituted therefor without altering the operation of the essential elements. Secured to one end portion of member I2 is a ferrule it, which extends therebeyond a sufficient distance toreceive an eraser l8. A boss 2!! is formed in said ferrule to extend inwardly into the body of said member 12 whereby these parts are secured toge-ther.

Mounted on ferrule it for longitudinal movement thereon is a sleeve 22, having a longitudinal recess 24 formed in the inner wall thereof, with its ends spaced apart from the outer ends respectively of said sleeve, thereby producing end walls 26. A boss 28, integral with ferrule i6, is adapted to fit in recess 24 to serve as a stop to limit the longitudinal movement of sleeve 22, and also to prevent relative rotation of the sleeve on the ferrule. In the assembly of these parts, which are preferably made of materials that are slightly resilient, it is possible to force the sleeve 22 to position over boss 28 where it remains dur-- ing the operation of the pencil.

In alignment with boss 28 and formed outwardly from ferrule Iii, are bosses 38 and 32, which are positioned respectively adjacent the inner and outer ends of ferrule l6. These bosses 30 and 32 are of less height than the center boss 23, so that the sleeve 22 may be moved thereover by the operator.

Referring to Figs. 4 and 6, wherein the two positions of the sleeve are shown, it will be observed that when the pencil is in use as shown in Fig. 4:, boss 28 is in engagement with the outer end wall 26 of the recess, and boss 32 is exposed to receive the tubular sheath 34. The presence of the boss 32 causes a tight fit of the sheath, whereby it is secured against accidental dislodgement. When the pencil is closed as shown in Fig. 6, for carrying in the pocket, the sleeve 22 is moved outwardly to cover eraser i8 as the boss 28 rests against the inner wall 25, and the lower 0 boss 36 is exposed to receive the sheath 34 to secure it in position to cover the lead carrying member. It will be noted that the lead and the eraser are both shielded when the parts are in position as shown in Fig. 6. Where the pencil is in the operative position as shown in Fig. 4, the eraser may be exposed for use by simply removing sheath 34.

The outer end of the sheath 34 is closed in some suitable manner as by means of a plug 36, which is tightly fitted therein. The inside diameter of the sheath 34 is such that when fitted over bosses it) or 32, the sheath will be slightly distorted and .a tension will be set up between the parts sufiicient to cause a definite relative relation of the parts.

Referring now to Figs. 9 and 10, wherein the bosses on the ferrule are transversely offset, it is apparent that the sleeve when positioned thereon, will be slightly distorted due to the fact that the lower bosses 30 and 32 will not rest in the recess 24, but will contact the inner wall of the sleeve.

It is apparent that I have produced a pencil that is economical and simple in construction and one that will function to produce a well proportioned pencil for writing and also effectually protect the lead and eraser when in the closed position.

What I claim is:

1. A pencil of the character described comprising a lead carrying member having a ferrule secured to one end thereof; a sleeve mounted for limited longitudinal movement on said ferrule to selectively extend beyond the opposite ends thereof; a sheath adapted to telescope said lead carrying member, and engage said ferrule; and a boss on said ferrule adapted to engage the inner wall of said sheath to frictionally secure said sheath in the operative position.

2. A pencil of the character described comprising a lead carrying member having a ferrule secured to one end thereof; a sleeve mounted for limited longitudinal movement on said ferrule and adapted toextend beyond the outer end thereof; a sheath adapted to telescope said ferrule; and a boss on said ferrule adjacent each end thereof adapted to selectively engage the inner wall of said sheath to secure it in the operative position.

3. A pencil of the character described comprising a lead carrying member having an outwardly projected ferrule secured at one end thereof; a sleeve mounted for longitudinal movement on said ferrule to selectively extend beyond the opposite ends thereof; means for limiting the longitudinal movement of said sleeve on said ferrule; means to prevent relative rotary movement of said sleeve on said ferrule; and a sheath adapted to telescope said ferrule to selectively cover said pencil and eraser.

4. A pencil of the character described comprising a lead carrying member having an outwardly projected ferrule secured at one end thereof; a sleeve mounted for longitudinal movement on said ferrule and adapted to extend beyond the outer end thereof; means for limiting the longitudinal movement of said sleeve on said ferrule; means to prevent relative rotary movement of said sleeve on said ferrule; a sheath adapted to telescope said ferrule to selectively cover said pencil and the outer end of said ferrule; and a boss at each end portion of said ferrule to selectively engage the inner wall of said shield whereby it is frictionally held in the operative position.

5. A pencil of the character described comprising a lead carrying member having an outwardly projecting ferrule secured to one end thereof; a sleeve mounted for longitudinal movement on said ferrule; means for limiting the outward movement of the outer end of said sleeve to a point beyond the outer end of said ferrule, and the inner movement thereof to a point intermediate the ends of said ferrule; and a sheath adapted to frictionally engage either end portion of said ferrule.

6. A pencil of the character described comprising a lead carrying member having an outwardly projected ferrule secured at one end thereof; a sleeve, having an internal longitudinal recess formed therein, mounted for longitudinal movement on said ferrule; a boss adjacent the central portion of said ferrule adapted to be positioned in said recess to limit the relative longitudinal movement of said sleeve; and a relatively low boss on said ferrule adjacent each of its ends adapted to be selectively exposed from beneath said sleeve, to frictionally engage the inner wall of a tubular sheath when the same is fitted over said ferrule.

7. A pencil of the character described comprising a lead carrying member having an outwardly projected ferrule secured at one end thereof; a sleeve, having an internal longitudinal recess formed therein, mounted for longitudinal movement on said ferrule; a boss adjacent the central portion of said ferrule adapted to be positioned in said recess to limit the relative longitudinal movement of said sleeve and to preclude relative rotation thereof; and a relatively 10W boss on said ferrule adjacent each of its ends in longitudinal alignment with said first named boss and adapted to be selectively exposed from beneath said sleeve, to frictionally engage the inner wall of a tubular sheath when the same is fitted over said ferrule.

8. A pencil of the character described comprising a lead carrying member; a ferrule secured to one end of said lead carrying member with one of its ends extending outwardly therefrom; a sleeve having a longitudinal recess formed in the inner surface and intermediate the ends thereof; a boss on said ferrule adapted to be positioned in said longitudinal recess to limit the relative longitudinal movement of said sleeve whereby its outer end may be positioned beyond the outer end of said ferrule and to secure it against rotary movement relative to said ferrule; and a tubular sheath adapted to telescope said ferrule and selectively cover said pencil and eraser.
